What to look out for when choosing a 400% casino bonus?

400% Casino Bonus

For £100 that you deposit, a 400% match bonus means you’ll play with £500. But don’t let this large sum of money draw you in too easily. Due to the high increase of your deposit, there will be clauses and conditions that impede you in order to protect the profit of the casino who has just turned your £100 into £500.

The rules may be that you need to wager the bonus 40x before you can withdraw any winnings. Also, part of the wagering requirements may be that you have to play on a specific game before the wagering starts.

The casino may also limit the maximum and minimum bet amount on a chosen slot whilst you are using your bonus so that you don’t end up going through the wagering requirements too quickly.

The casino may require you to enter a bonus code or promo code in order to activate the bonus. This would usually be mentioned in the T&C’s or alternatively you can contact customer support after you have deposited. Make sure you do this before you start playing, as once you have begun, you may not be eligible to claim the bonus.

Be sure to check whether the bonus offer has an expiry date as you don’t want to opt into a deal when you are unable to meet the wagering requirements in time. 

Always keep an eye out for the wagering requirements on 400% casino bonuses and their max winnings

It might be a boring part, but we strongly recommend that you do not rush these steps. Without checking our review or reading some of the T&Cs you might be in for a nasty surprise later. It’s worth spending 5 to 10 minutes from the time you find a new bonus deal, to depositing at that casino. During that time, make absolutely sure this is where you want to spend your money. We will always try to make things easier for you by transparently reviewing and promoting the online casino deals.

Why take advantage of Mr Bet 400% casino bonus?

With the welcome package being so generous, this usually means that there has to be some catch involved. Well, there isn’t! The 400% casino bonus is great because it is split between four deposits so once the first deposit offer runs out, the second deposit offer is there to save the day and so on. Also, the minimum deposit amount is low so you don’t have to fork out too much in order to qualify for the offer.

The welcome package has 45x wagering requirements attached, and although this may seem a bit high at first glance, it is at the lower end of the scale for other offers in the 400 casino bonus category.

400% casino bonus + 🧲cashback as an existing player?

Although it is not common, it is absolutely possible. Besides claiming a 400% casino bonus at Mr Bet, players can also receive 5% weekly cashback on top of the lucrative welcome package. Being able to claim cashback gives players the chance to receive some of their net losses each week in order to boost their account balance.

It is rare to find 400% deposit match casinos in the UK that will honour this offer on your first deposit. Bonus tax regulations do sometimes deter casinos from offering such lucrative bonuses as they need to protect their finances.

In line with the General Betting Duty and gambling taxes, operators are obliged to pay a certain percentage in tax on all free or discounted bets online. The percentage they pay depends on the type of casino and the type of betting they offer. This pay point of income tax, has to be paid by online casinos as part of the RGD (Remote Gaming Duty). This meaning that 21% of their profits has to be paid to the UK Government. This percentage can vary between countries and their different legislations; therefore, it is easier to see such first deposit deals in Curacao and Malta licenced casinos such as La Fiesta and Superlines Casino.

However, when we find such deals on 1st deposits in the UK, we will list them on the site for you to enjoy.

Sometimes casinos will split the bonus over 3 deposits. For example, if a casino offer is 400% match casino bonus up to £100 and 50 free spins on a specific slot. The first deposit maybe 200% deposit match and 20 free spins, 2nd deposit may be 100% deposit match and 10 free spins then 3rd deposit may be 100% deposit match and 20 free spins. So, you are still getting the full amount but will only be able to claim the offer if you split your deposit amounts over 3 transactions and your maximum deposit match will be £100. So anything that you deposit over this amount will not count towards the bonus. 

Ask yourself the following questions:


What makes Casinobtc stand out from the rest?

Casinobtc was established in 2020 and has a Curacao casino license. They have over 1300 slot games so there will always be a game to suit every player. One of the first elements that sets them aside is the fact that they accept Cryptocurrency in the form of Bitcoin and Litecoin.

Gambling with Bitcoin and Litecoin has become more popular over the last few years and this could be put down to the lightning-fast withdrawals. Usually players would have to complete the KYC (Know Your Customer) process in order to receive their winnings from a casino. This procedure is in place to not only protect the casino from illegal activities like money laundering, but also to protect the players from fraudsters who may have gained access to their account and are trying to steal their winnings.

The welcome package that Casinobtc has on offer for new players is both rewarding and extensive. The package consists of a 900% deposit match up to £/$/€5000 bonus which is split over 5 deposits as follows: 

1️⃣st Deposit- 400% up to £/$/€1000 bonus with bonus code: WELCOME1

2️nd Deposit- 200% up to £/$/€1000 bonus with bonus code: WELCOME2

3️rd Deposit- 100% up to £/$/€1000 bonus with bonus code: WELCOME3

4️th Deposit- 100% up to £/$/€1000 bonus with bonus code: WELCOME4

5️⃣th Deposit- 100% up to £/$/€1000 bonus with bonus code: WELCOME5

The fact that the Casinobtc welcome package spans out over 5 deposits means that players can feel valued every time they deposit by being rewarded with a deposit match. Firstly, players will receive 5x their initial deposit amount when they first join the casino and take advantage of the welcome offer.

Furthermore, on the 2nd deposit players will have 3x their deposit amount to play with, then on the 3rd-5th deposits players will have double their deposit amount. The welcome package is designed in order to keep players returning to the casino and we can see why players would make a comeback at Casinobtc with this highly rewarding offer for new players

What is the difference between the UK deal and Non-UK deal at Captain Spins?

Firstly, regardless of what country you are registering from, Captain Spins Casino will treat you like the royalty of the ship with their rewarding welcome offers. Captain Spins has 2 casino licensesUK Gambling Commission and the Malta Gaming Authority, meaning they have passed the strict rules of both of them in order to have both bodies regulate their casino. This should put players at ease knowing that they are playing at a trustworthy and safe casino.

What do UK players receive when registering at Captain Spins?

The UK welcome offer consists of 520 bonus spins on Book of Dead Slot upon depositing a minimum of £20. The only thing to remember is that the bonus spins are split over the first four deposits as follows:

1️⃣st Deposit - Get 120 bonus spins on Book of Dead (Min. Deposit: £20)
2️nd Deposit - Get 120 bonus spins on Book of Dead (Min. Deposit: £20)
3️rd Deposit - Get 140 bonus spins on Book of Dead (Min. Deposit: £20)
4️th Deposit - Get 160 bonus spins on Book of Dead (Min. Deposit: £20)

The fact that the spins are split over 4 deposits is kind of like having a reload bonus, so each time you deposit you will have the bonus spins to play with on Book of Dead and also the money you have deposited. This is designed to keep you entertained for longer and keep returning to the casino in the long term. 

What Welcome offer can Non-UK players get when they sign up at Captain Spins Casino?

The Non-UK welcome package is a 400% deposit match up to N$/C$/€1200 bonus + 260 bonus spins. Again, like the UK welcome offer, this is split over four deposits as follows:

1️⃣st Deposit - 100% up to €300 and 50 bonus spins on Book of Dead (Min. Deposit: N$/C$/€10)
2️nd Deposit - 100% up to €300 and 60 bonus spins on Book of Dead (Min. Deposit: N$/C$/€10)
3️rd Deposit - 100% up to €300 and 70 bonus spins on Book of Dead (Min. Deposit: N$/C$/€10)
4️th Deposit - 
100% up to €300 and 80 bonus spins on Book of Dead (Min. Deposit: N$/C$/€10)

Noticeably, the minimum deposit required to be eligible for the welcome package is lower than that for UK players. The second difference is that Non-UK players don’t receive as many bonus spins, however they do get a deposit match on their first 4 deposits.  With over 1500 games to choose from, there is always going to be a game for every type of player to use their deposit match bonus on.
